Unfortunately, the spam cleaner isn't working on my dev install. When running it manually (with all add-ons disabled), it just hangs, slows down my computer & eventually logs a fatal error in the error log:
ErrorException: Fatal Error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 815104 bytes) -library/Zend/Db/Statement/Mysqli.php:208
Occasionally, if I restart the mysql server, it'll work, but then it won't.
Any ideas on what's causing this?
